Abstract :
We focus on the change of the dynamical behaviour of an optically injected VCSEL by varying its material parameters with temperature. Dynamical characteristics of the system are studied via stability maps in the plane of frequency detuning versus injection strength calculated for different temperatures. One of the most clearly defined features of stability maps is the minimum of the Hopf bifurcation with respect to injected optical power. The calculated variation of the Hopf minimum with temperature is shown. It is concluded that the temperature dependence of injection-locked VCSELs has been simulated using a comprehensive model of the relevant material parameters.
